Description
The Model 265 3-Phase Monitor
continuously monitors 3-phase
Wye or Delta systems for
phase loss, low voltage and
phase reversal. When properly
adjusted, the Model 265
Monitor will detect phase
loss on a loaded motor even
when regenerated voltage is
present. The solid-state
sensing circuit drives an
internal relay, in a
fail-safe configuration, i.
e. , the relay is energized
when correct voltage and
phase rotation are applied.
Operating power for the Model
265 is drawn from the 3-phase
lines being monitored. An
adjustable timer delays
restarting of the load,
allowing up to five minutes
for compressor head pressures
to bleed off, in the event of
short-term power failures.
The Model 265 Monitor is not
sensitive to line current,
and can be used with any size
motor or compressor.
Automatic and manual reset
versions are available.
